Apply materials and get auto-updated BoQ

Apply materials and get auto-updated BoQ Get instant material estimates (Bill of Materials) for your project by applying materials and editing the structure of walls or slabs Amritha Krishnan

On applying material, we update object thickness and composition of the object. The updated thicknesses and composition can be viewed by clicking on Edit Class in Object Properties. The depends on:

  • Object type: whether the object is a wall, slab, column, flooring, etc

  • Material: whether the material is stone, glass, metal, wood, brick, etc

  • Material application type: By Face or By Object

BoQ update on applying Material by Object

Typically, default thicknesses for objects are updated when you apply the material to it By Object.

For example,

  • If you apply glass on a wall By Object, the material texture is applied, as well as its thickness is updated to 20mm.

  • If you apply stone on a wall By Object, the material texture is applied, as well as its thickness is updated to 300mm.

For some material types, applying the material By Object is also used to update the object’s finish. For example Colour and Tiles.

BoQ update on applying Material by Face

Typically, default finishes for all objects are updated based on the material applied By Face.

For example,

  • Applying stone to a wall by face adds a 19mm stone cladding fixed to the wall with a 12mm screed. The wall thickness increases by 31mm accordingly. This is reflected in the Bill of Materials as Stone Cladding.

  • Metal finish is considered as a 4mm cladding fixed with a generic 19x19mm support. Quantities are calculated for both in sqm.

  • Wood finish is considered as a 12mm wooden cladding fixed with a 12mm support. Quantities are calculated for both in sqm.

Check the construction of BIM objects using Edit Structure

You will be able to visually see the change in the object thickness when you apply a material. Material quantities are calculated based on these updated thicknesses. You can, of course, manually override any of the default values for each material, and material quantities will be updated accordingly.

To view or change the construction of a wall, select the wall, and in Object Properties, click on Edit Structure. Here you can add details like an air gap, waterproofing, or thermal insulation layers. You can also change the thickness of existing layers, and delete layers.
